STRUCT MTK_JPEG_FMT(9)

💖 NAME 💖

struct mtk_jpeg_fmt — the driver's own internal lil cheat sheet for color formats ✨ (this is a Kernel API Manual page, btw, so you know it's the real deal 👑)

🎀 SYNOPSIS 🎀

okay so here's the whole struct, bestie, every field exactly as it lives:

struct mtk_jpeg_fmt {
    u32 fourcc;
    u32 hw_format;
    int h_sample[VIDEO_MAX_PLANES];
    int v_sample[VIDEO_MAX_PLANES];
    int colplanes;
    int h_align;
    int v_align;
    u32 flags;
 };

🦋 Members 🦋

the way that each of these has a job and they all ate 💅

• fourcc — the fourcc code, and it's 0 if it's not applicable, periodt
• hw_format — the hardware format value 🔥
• h_sample — horizontal sample count of the plane, measured inside a 4 * 4 pixel image
• v_sample — vertical sample count of the plane, also inside a 4 * 4 pixel image 🎀
• colplanes — number of color planes, and lowkey important: it's 1 for packed formats
• h_align — horizontal alignment order, meaning align to 2^h_align ✨
• v_align — vertical alignment order, meaning align to 2^v_align ✨
• flags — flags that describe the format's applicability 🌸
